  • Patent number: 8162721
    Abstract: In through-feed grinding workpieces by grinding stones rotating around the axes of spindles, the spindles are tiltably held by elastic holding means around tilt axes substantially orthogonal to the direction of exit and entrance of the workpieces with respect to the grinding stones. When a grinding loads are imposed on the entrance sides of the grinding stones, the spindles are tilted by offset loads around the tilt axes against the force of urging means in such a manner that the axial displacement and the exit displacement of the grinding stone due to the offset load are substantially the same. The grinding stones are reset around the tilt axes by the elastic holding means immediately before the end of processing at which time the axial displacement is smaller. This makes it possible to reduce the number of defectively ground articles coming from the through-feed grinding and reduce the wear in the grinding stones.

  • Publication number: 20090111365
    Abstract: In a swivel device, a swivel head provided with a plurality of tool spindles thereon is mounted on a support base to be turnable about a swivel shaft being upright on the support base. An annular space portion is formed between the support base and the swivel head in coaxial relation with the swivel shaft. The tool spindles each mounting a grinding wheel are arranged on the swivel head to extends in a horizontal plane which crosses the annular space portion at about a mid position in the vertical direction of the annular space portion. A direct drive motor is built in the annular space portion so that a driving center of the direct drive motor is at almost the same height as the horizontal plane including the axes of the grinding wheels. Thus, the swivel device can lower the positions of the rotational axes of the grinding wheels and is rigid against inclination caused by grinding resistance acting on the grinding wheels.

  • Publication number: 20090104854
    Abstract: In prior art, an additional radial inward movement that is performed in accordance with a rotating cam disk is imparted on the grinding disk in order to relief-grind the cutting teeth and the chamfer of taps and the cutting teeth of thread formers. The invention relates to a cam disk which can be rotated about an axis and is provided with a control cam. The control cam forms a group of curves according to a large number of possible undercut contours on the grinding teeth of the tap or thread former, which are to be relief-ground. In order to obtain a specific undercut contour on a cutting tooth, a limited angle of rotation is selected from the control cam. The area is mechanically, optically, or electronically scanned by means of a scanning device. To this avail, the cam disk performs an oscillating rotary movement only above the selected section of the control cam.

  • Patent number: 6361421
    Abstract: The invention relates to a belt grinder of which the supporting tables (13, 14) are arranged in relation to the grinding unit (11) and hence the grinding belt (12) in such a way that tables need not be adjusted at the same time as the grinding unit is pivoted, while nevertheless the gap (z) between the grinding unit and the edges of the tables remains minimal. Such an arrangement is obtained if the value one minus the cosine of half the maximum pivoting angle (y) multiplied by the direct distance (d) between the tables edges is divided by two and the cosine of half the maximum pivoting angle (y) and gives a result acceptable for practical use and compliance with the standards and safety specifications for the gap (z) between the table edges and the grinding unit.
